Description
General Description & Background Information:
In this course, we'll develop a WLAN (wireless local area network) application using the ESP-IDF (Espressif IoT Development Framework). WiFi is commonly incorporated into many IoT and Industrial IoT solutions and is the basis of the application developed in this course.
The ESP32 is a series of low-cost, low-power, SoC (system on a chip) series of microcontrollers with integrated WiFi and dual-mode Bluetooth. The ESP-IDF is Espressif's official IoT Development Framework for the ESP32. It provides a self-sufficient SDK (software development kit) for any generic application development, using programming languages such as C and C++. ESP-IDF currently powers millions of devices in the field, and enables building a variety of network-connected products, ranging from simple light bulbs and toys, to big appliances and industrial devices.
The ESP-IDF runs FreeRTOS, which is widely used in embedded systems, so the techniques and knowledge you gain while developing IDF-based applications for the ESP32 will translate well should you use other MCUs running FreeRTOS. Additionally, the FreeRTOS kernel of the ESP-IDF is modified for multicore support and we will utilize both cores of the ESP32 in this course.
If you are interested in working with the ESP32 and are serious about improving your embedded software development skills while getting to know this incredible SoC, then harnessing the capabilities of the ESP-IDF directly, is an excellent way to go.
The IDF is well designed, and once you get going, implementing new features becomes a breeze. Further, any new updates, bugfixes, or changes to the ESP-IDF can be immediately available to you in a flexible way without having to wait for the Arduino port to be written.
About the Course:
For many, the best way to learn is to start with a project, which is why in this course, I have created a WLAN application as a learning tool - as opposed to demonstrating tiny examples that you could easily find online.
The intended outcome of this course, is that you gain insight from the application code and inspiration for your own projects.
By working through this project, programming step-by-step through each lesson, I'm confident that you will feel comfortable developing an extensible WLAN application using the ESP-IDF or any application using the ESP-IDF, as it will become apparent how to create your own plan of action when using Espressif's IoT Development Framework --> utilizing the Espressif documentation, looking up the API reference and relevant functions, gaining inspiration from existing examples provided by Espressif and applying what makes sense to accomplish your goals.
Furthermore, in this course we will not focus on theory, it is a 100% practical, application programming course, where you learn by doing. However, I will briefly present background information about the ESP-IDF application programming interface that applies to each section and a brief overview of the application requirements for each section --> what will be accomplished and how we are going to accomplish it using the ESP-IDF.
Lastly, I have chosen to develop this project utilizing the ESP-IDF Eclipse Plugin (available for Windows, MacOS, and Linux), which provides an all-in-one installation that includes the Eclipse IDE, and all prerequisites required for the ESP32, enabling us to get started with programming, flashing and monitoring the ESP32 directly after the install --> this setup process is quite easy and efficient, especially for Windows users.
